Netflix allows up to 5 devices on one account, but only 2 can be logged in at the same time.
I think there is a more expensive account that allows more....
That's strange. We have a basic account, was $8 until this month raised to $10. And we have 5 devices alone at our home that use Netflix, and a couple others in use by two relatives in two other homes - that's 7 devices at least, all on our single account. Maybe a glitch? I don't know how many logged in simultaneously, haven't tracked that. Will have to try more than 2 simultaneously. Anyway, we love Netflix and wouldn't mind paying more.
